INTRODUCTION

The H series resistors are oil-filled, hermetically sealed ultra

precision resistors and are used as secondary standards for

metrology applications.

The hermetic sealing eliminates the ingress of moisture and

oxygen, while the oil acts as a thermal conductor, thus

eliminating the long-term degradation elements of unsealed

resistors, while at the same time allowing the device to

accept short periods of overload without degradation.

Vishay’s Bulk Metal

Foil outperforms all other resistor

technologies available today for applications that require

precision and stability. When combined with the hermetic

sealing and oil filling, the H series resistors become

the most

precise and stable resistors available.

With accuracies of 0.001 %, a resistance range from 5

to 1.84 MΩ, and long term shelf life of less than 2 ppm,

these devices are virtually secondary standards that can be

carried in sets for daily or periodic calibration of factory

measurement equipment.

The H series is available with laboratory and metrology

level precision and long-term stability with additional

in-house oriented processes such as: chip stabilization,

special TCR plotting, additional treatments for ultra

stability and special post manufacturing operations

(PMO). (Please refer to the last page)
